Abstract

Background: Studies had been performed on blends of natural rubber (NR) and poly vinyl acetate (PVAc). The two polymers had been characterized based totally on their physicochemical properties and used in paint production. Results received confirmed that viscometric measurement and density of the polymers did now not fluctuate much. Five paints of distinctive compositions labeled; Paint 1 (100% PVAc), Paint 2 (100% NR), Paint 3 (75% NR: 25% PVAc), Paint 4 (50% PVAc: 50% NR), and Paint 5 (25% NR: 75% PVAc) the usage of popular emulsion paint formula and approach of manufacturing have been employed. NR and PVAc are well-matched as binders in emulsion paint production. Therefore, NR/PVAc blends may want to be used as a binder in the coating industry as a choice to PVAc binder-based emulsion paint.

Objectives: This study aims to assess the Preparation and characterization of binary blends of NR and oxidized NR with PVAc.

Methods: This is an observational study. The study used to be carried out with the samples in the Department of Applied Chemistry and Chemical Engineering, Islamic University, Kushtia-7003, Bangladesh. The duration of the period from Data was entered in MS Excel and Statistical analysis was done using SPSS trial version.

Results: This study shows that the according to Constituent, Cellulose was 43.4822%, Alpha-Cellulose was 34.8427% and Cellulose was 8.6395%. And according to Source, Rice Straw was 32.15% %, Sugarcane was 41-43%, Rye Straw was 31.8-42.64%, Corn Stalks were 29.80% and Wheat Straw was 34-40%.

Conclusion: The residences of opacity, wash ability resistance, and putting contact drying time of emulsion paint with modified NRL binder and modified NRL combination with PVAc can be multiplied using in addition editing natural rubber latex (NRL) molecules. Modifications are needed to rise the adhesion of natural rubber latex (NRL). The adhesive characteristics of natural rubber latex (NRL) can match the characteristics of general adhesives such as PVAc.
